![]() Block ciphers may be capable of operating on more than one block size, but during transformation the block size is always fixed. The initialization vector is used to ensure distinct ciphertexts are produced even when the same plaintext is encrypted multiple times independently with the same key. ![]() The IV has to be non-repeating and, for some modes, random as well. Most modes require a unique binary sequence, often called an initialization vector (IV), for each encryption operation. A mode of operation describes how to repeatedly apply a cipher's single-block operation to securely transform amounts of data larger than a block. A block cipher by itself is only suitable for the secure cryptographic transformation (encryption or decryption) of one fixed-length group of bits called a block. In cryptography, a block cipher mode of operation is an algorithm that uses a block cipher to provide information security such as confidentiality or authenticity. For "method of operation", see Modus operandi. If you plan on having your dashcam installed by a professional, don’t miss on the chance to have them install the Power Magic Pro as well."Mode of operation" redirects here. Turn Parking Mode ON/OFF: with the switch OFF, the Power Magic Pro will power your BlackVue dashcam only when the vehicle’s ignition is on.Set a voltage cutoff value (12V by default): as soon as the vehicle’s battery reaches that voltage, Power Magic Pro will stop powering the dashcam, in order to prevent battery discharge.With a bit of planning, Power Magic Pro allows for a very stealthy installation, with no visible cable. For professional installationįor users who are not afraid to work with the fuse panel of their vehicle, the Power Magic Pro is a great accessory that enables Parking Mode with a lot of control. When voltage drops below cutoff value or the timer expires, Power Magic Pro stops powering your dashcam to preserve your vehicle’s battery. With Power Magic Pro, your dashcam is powered as long as your battery maintains sufficient voltage to start your vehicle. Simply hardwiring your dashcam without Power Magic Pro would risk depleting your vehicle’s battery with long Parking Mode sessions. It powers your dashcam and protects your vehicle’s battery. Power Magic Pro is the hardwiring kit by BlackVue. You can connect multiple Expansion Batteries in sequence (daisy-chain) to the Power Magic Ultra Battery. More than double the Power Magic Ultra Battery capacity with Power Magic Expansion Battery (6600mAh). See at a glance available capacity, time to full charge (when charging), expected time available (when powering the dashcam) and change settings. The status of the Ultra Battery can be checked via the BlackVue Battery app (iOS/Android). Hardwired installation for rapid charging (9A): the Ultra Battery charges itself in under 40 minutes. The Power Magic Ultra Battery can be plugged into your vehicle’s cigarette lighter socket or hardwired via the vehicle’s fuse panel.Ĭigarette lighter socket installation (5A): the Ultra Battery charges itself fully in less than 80 minutes. The Power Magic Ultra Battery is kept ultra compact thanks to its aluminum casing optimizing heat dissipation. On a full charge, Power Magic Ultra Battery can power a single dashcam for over 28 hours or a dual-channel dashcam for over 20 hours in Parking Mode. High capacity for extended Parking Mode sessionsĬapacity: 6000mAh / 12.8V / 76.8Wh. Two USB ports let you charge other electronic devices such as phone, tablet or a Wi-Fi hotspot to enjoy BlackVue Cloud. The Power Magic Battery Pack is small enough to fit in a glove box. Last, LiFePO4 batteries have an overall higher lifespan (based on number of charge/discharge cycles) when compared to lithium-ion batteries. Note that this is also why our dashcams use a supercapacitor instead of a battery. Indeed, in a vehicle parked in the sun, temperatures can reach levels at which lithium-ion batteries could pose a safety hazard. LiFePO4 batteries are highly resistant to heat, which is critical to ensure safe operation in a vehicle. Unlike conventional lithium-ion battery packs found in consumer electronics like phones or laptop computers, the Power Magic Battery Pack is of the LiFePO4 (lithium iron phosphate) type. When ignition is OFF, the Power Magic Battery Pack keeps your BlackVue powered for up to eight (8) hours-for a dual-channel dashcam-or twelve (12) hours-for a single-channel dashcam. It charges itself fully in approximately one hour. While ignition is ON, the Power Magic Battery Pack charges itself while powering your BlackVue. The Power Magic Battery Pack simply plugs into your vehicle’s cigar lighter socket and provides a female power socket to power your dashcam.
